W 636-2RS1 Bearing Product Overview & Core Advantages
The W 636-2RS1 is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubricated grease, providing long-term, maintenance-free operation by effectively excluding contaminants and retaining lubrication. This bearing is engineered to handle primarily radial loads and is suitable for a wide operating temperature range, making it an ideal choice for applications demanding high precision and durability in challenging environments.
Model Code Breakdown

| 636 | Standard bore diameter (6 mm), outside diameter (22 mm), and width (7 mm) dimensions |
| 2RS1 | Contact rubber seals on both sides, providing superior protection against contamination and moisture |
W 636-2RS1 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and stainless steel construction provide reliable performance and high resistance to corrosion, ensuring a long service life.
- Effective Sealing: The 2RS1 double seals effectively prevent the ingress of contaminants and the egress of grease, making the bearing maintenance-free and suitable for dirty or humid environments.
- Pre-Lubricated for Longevity: Filled with high-quality grease, the bearing is ready for immediate use and offers smooth operation across its specified temperature range (-30° to 120 °C).
- Precision Tolerances: Manufactured to P0 tolerance class and standard radial internal clearance (CN), ensuring consistent performance and ease of integration into precision assemblies.
